Under Road Crossing: MULTIduct™

MULTIduct™ is perfectly suited for under road crossings and used within the Traffic Signals and Street Lighting (TSSL) industry in the UK.

MULTIduct was specified by Worcester City Council due to its high strength. This type of installation would normally be completed using twinwall circular ducting. As MULTIduct™ is significantly stronger, it can be buried much shallower than conventional products, meaning reduced excavation, removal of spoil and backfill. As there are no spacers for separation of duct, the excavation is narrower. These factors combined result in faster installations which save time, money and allow roads to re-open quicker.

MULTIduct’s flat internal profile makes it easy for cable installers to pull cables through the ducting to connect inside the STAKKAbox™ access chambers (shown). The product lies flat and straight in the trench and does not impart the same pulling forces on the cable.

AX-S™ Composite covers are supplied with Louvre frames which allow surrounding materials to be placed right up to the outside of the frame, reducing the need for a concrete fillet. This fillet is prone to cracking when trafficked continuously by slow moving vehicles.
